Calcula:

- [3 x (4 - 6) - 2 ]

2 - [-3 x (2 - 3 - 6) + 8]

2 x [ - 9 x ( - 9 x ( - 9 + 3 - 6) + 5]

- 27 : [ - 3 x ( - 9 - 6) - 72 : 2]

- 7 x [5 x ( - 2 + 6) - 2 x ( - 5 + 9) ]

8 : (15 - 7) - [3 x (4 - 6) - 2]

9 : (12 - 3) - [3 x (5 - 8) - 3 ]

Gracias :`D

Answer 1

1. - [3x(-2)-2]:
- [-6-2]:
- [-8]:
8

2. 2- [-3 x (-7) + 8]
2- [ +21 +8]
2- [ +29]
-27

3. 2 x [ -9 x (-9 x (-12) +5 ]
2 x [ -9 x 108 +5]
2 x [ -967 ]
-1934

4. -27 : [ -3 x (-15) -72 :2]
-27 : [ -13'5]
2

5. -7 [ 5 x (4) -2 x (4)]
-7 [ 20 - 8]
-7 [ 12]
-84

6. 8 : (8) - [ 3 x (-2) -2]
1 - [ -8 ]
8

7. 9: (9) - [ 3 x ( -3) -3]
1 - [ -6 ]
6

Espero que te sirva
